LEGENDRE CINQ-MARS, OF SAN FRANCISCQ, CALIFORNIA, ASSIGNOR TO CONSERVATIVE HEATING COMPANY, OF SAN FRANCISCO, CALIFORNIA, A CORPORATION.

Application filed October 12, 1916.

To all whom it may concern:

Be it known that I, Lnonn DRE CINQ-MARS, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in VVater-I-Ieaters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in water heaters of the type employing gas as fuel, the present device being designed primarily to be used for heating houses, although it is to be understood that it may Well be employed for other purposes.

The object of the invention is to provide a simply constructed yet highly efficient heater provided with novel means whereby any moisture of condensation will be collected in the base of the heater and drained therefrom.

With this general object in view, the invention resides in certain novel features of construction and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which:

Figure 1 is a front elevation of the improved heater with parts in section;

Fig. 2 'is a vertical sectional view on the plane of the line 22 of Fig. 1;

Fig. 3 is a horizontal sectional. view out above the water heating box on the plane indicated by the line 83 of Fig. 2;

Fig. at is a similar view out through said box on the plane of the line 4-4L of Fig. 2;

Fig. 5 is a perspective View of the base;

nates the base of the improved heater, this base being of rectangular hollow formation with an open top and an inclmed bottom 2.

Specification of Letters Patent.

' Patented Feb. 2c, 1917.

Serial No. 125,262.

This bottom is preferably inclined downwardly from its rear to its front end and at the latter is provided with a drip 3 whereby any moisture of condensation may be conducted from the base. The front of the base 1 has formed therein a notch 3* through which the front ends of a pair of gas burners 4L extend, said burners being located in the base as shown.

The upper edges of the parallel sides 5 of the base 1 are extended laterally outward throughout their lengthsas indicated at 6 and then vertically as disclosed at 7, thereby providing a pair of flanges L-shaped in cross section which constitutes seats to support a water heating box 8, said flanges having L-shaped internal lugs 6'" which space the lower corners of said box from the portions 6 and 7 sufficient distances to permit moisture to travel downwardly from the exterior of said box into the base 1. Other lugs 10 space the box 8 from the front and rear sides of the base for the same purpose. The rectangular water heating box 8 is open at its bottom and is provided with hollow side walls 9 and with a hollow top wall 10, the latter being inclined upwardly and rearwardly and having at its upper end a transverse inlet slot 11. A cold water inlet 12 is provided for admitting water into the hollow walls 9 and 10, while a pair of threaded bosses 13 rise from said wall 10 for the purpose of discharging the water when heated. The bosses 13 are disposed one on each side of the slot 11 at which points the heat discharged through said slot will maintain the parts in question at a high temperature. The front wall of the box 8 ispreferably formed with an opening 1 1 through which a pilot 15 may be lighted. The base 1 and box 8 may be constructed in any suitable manner and .of appropriate material, both of these parts, however, being preferably cast. In thus forming the box 8, the lower half of the hollow wall 10 will be preferably in the form of a thin copper plate as indicated at 16, whereby heat within the box may act to great advantage on the water above this plate. The entire box 8 is preferably though not necessarily formed of brass.

Connected by, nipples or the like 17 with the bosses 13 is a pair of headers 18 to which the lower ends of zig-zag water heating pipes 19 are brazed or otherwise secured. The upper ends of the pipes 19 are similarly secured to headers 20 from which a pair of pipe sections 21 rise, these two sections being connected through the instrumentality of a short length of pipe 22 having at one end a T-coupling 23 from which a hot water pipe is adapted to lead.

The headers 20 have laterally extending ears 24: formed on their ends, these ears being provided for the anchoring of a suitable casing 25 which surrounds the pipes 19 and is provided at its top with a heat outlet 26. The lower end of the casing 25 extends around the upper portion of the box 8 and isspaced therefrom a sufficient distance to permit moisture of condensation to drip from the inner side of said casing 25 onto the exterior of the box 8. From the latter this moisture will flow into the base 1 and will bedrained therefrom through the drip 3. The front end of the top wall 10 of box 8 is also provided with cars 26 to which the casing 25 is secured.

Oppositely inclined heat checking plates 27 are disposed adjacent the numerous reaches of the pipes 19 in order to prevent the direct upward passage of heat, said plates serving to confine said heat more or less around the pipes 19 whereby more'efiicient heating will result. The plates 27 also serve to collect moisture dripping from the pipes 19 and to convey such moisture to the inner side of the casing 25, the lower ends of said plates being spaced sufliciently from said casing to permit this moisture to descend. Tight connection between the side edges of plates 27 and, the casing 25 is effected by stay bolts 28 but the lower edges of said plates are not in fluid tight contact with the casing in order that moisture may drip from these edges.

For the purpose of allowing access into the casing 25 for the purpose of cleaning the same and the parts therein, a door 29 is preferably provided. This door as well as the casing will preferably be constructed of inner and outer shells with a packing of insulating material therebetween.

By constructing the improved heater in the manner shown and described it will be obvious that the same will be highly eflicient and durable, particular emphasis being laid upon the numerous features of construction which permit the collection of moisture and prevent the same from dripping upon the Copies of this patent may be obtained for burners. By these features, numerous undesirable results are prevented.

In the foregoing, I have described certain specific details of construction for the attainment of probably the best results and in the drawings such details have been shown. It is to be understood, however, that within the scope of the invention as claimed, numerous changes may be made.

I claim:

l. A. water heater comprising a hollou base having an open upper side, a burner in said base, a water heating box mounted on said base and having an open bottom, said box having hollow side and top walls and the latter having a heat outlet opening therethrough, a water inlet into the hollow walls, a water outlet therefrom at one edge of said heat outlet, zig-Zag water heating pipes rising from said. water outlet, and a casing around said pipes having a heat outlet.

2. A water heater comprising a hollow base having an open upper side provided with angular flanges along two of its edges, a burner in said base, a water heating box received between said angular flanges and spaced therefrom sufliciently to permit moisture to pass from the exterior of said box into said base, said box having hollow side and top walls and an open bottom, said top wall having a heat outlet formed therethrough and having a hot water outlet adjacent said heat outlet, while the side walls are provided with a cold water inlet, zig-zag heating pipes rising from said hot water outlet, a casing surrounding said pipes and likewise surrounding the upper portion of the'aforesaid water heating box, said box and casing being secured together but spaced sufficiently to permit moisture to pass between the two, and a plurality of opposed inclinedheat checking plates in the casing to prevent the direct discharge of heat therethrough and to collect moisture dripping from the heating pipes, the lower edges of said plates being spaced from the casing sufliciently to permit the discharge of such moisture.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
